You may already know that the scanners that show a full nude body picture to security at the airport are going away - the TSA finding that not only did the machines produce humiliation, they also produced a lot of x-rays. Now, they'll be using machines that scan using radio waves, and producing only a blurry figure on the screen. But will we have to put up with getting scanned forever?

(Napolitano) "We don't put scanners in airports for our health."

...Homeland Security chief Janet Napolitano at a forum at the Wilson Center in Washington.

(Napolitano) "Those scanners are very valuable. Why? Because aviation remains a threat."
